Herbal abortifacients?? HELP

So my period is now late by two weeks. Pregnancy is a possibility, though my boyfriend and I do use new condoms EVERY time AND he pulls out during my fertile week to stay on the safe side. But I'm usually very regular... And I'm two weeks late. I'm 20 and I cannot care for a child and cannot afford to be pregnant (trying to get into med school here). I'm looking at natural options and  considering herbal abortifacients. But I know nothing about this so please someone with knowledge about this stuff HELP
